Multi-frame blind deconvolution of astronomical images

T. J. Schulz


Maximum-likelihood estimation techniques are presented for the problem of forming object estimates from turbulence-degraded images when the point-spread functions are unknown. The inability of unconstrained maximum-likelihood methods to form meaningful estimates is acknowledged and iterative algorithms are derived for estimating the object using both a penalized maximum-likelihood method and a parameterization of the point-spread functions as phase errors distributed over an aperture.
